Abstract
The utility model a freezing insulated joint of a rail, which comprises a thickened clamping plate (1), an insulated glue layer (3), the rail (5), an insulated plate of a rail end (8), an insulated sleeve pipe (6) and a high-strength bolt (7). The utility model is characterized in that two groove-shaped steel plates (2) are added between the insulated glue layer (3) and the rail (5), and the insulated glue layer (3) is used to make the thickened clamping plate (1) and the groove-shaped stel plates (2) heated and solidified to be bonded to be made into an integral glue connection insulated clamping plate. The utility model has the characteristics of high structure strength, good insulated performance, convenient assembly and diassembly and wide application range.
Description
The utility model is a kind of insulating joint that railway track is used that connects, and particularly relates to rail and freezes insulating joint.
At present, having on the rail track of track circuit, be used to connect the rail insulated joint structure, mainly contain two types: a kind of is common insulating joint structure, it has simple in structure, easy accessibility, advantage that price is low, but have the shortcoming that structural strength is low, joint resistance is little, joint disease is many, maintenance load is big, this kind insulating joint is a weak link outstanding on the circuit, and influences the speed-raising of rail track; Another kind of for glueing joint the insulating joint structure, it has bulk strength height, good insulation preformance, advantage that maintenance load is few, but shortcomings such as existence carrying inconvenience, construction bother, fault is difficult to processing and on the high side, and this kind insulating joint structure can not be used at some positions of switch area, therefore is unfavorable for the development of trans-section seamless railway.
The purpose of this utility model provides a kind of structural strength height, good insulation preformance, and is convenient to dismounting and the wide rail of the scope of application freezes insulating joint.
The purpose of this utility model is achieved in that a kind of rail freezes insulating joint, comprise thickening clamping plate, insulation glue-line, rail, fiber end post, insulation sleeve, high-strength bolt, between described insulation glue-line and rail, increase by 2 troughing plates, and will thicken clamping plate and troughing plate through heating cure and the bonding splicing cleat insulator of making one with the glue-line that insulate.
The utility model compared with prior art has following advantage: be coupled to rail with splicing cleat insulator, fiber end post, insulation sleeve and high-strength bolt and freeze insulating joint, than common insulating joint intensity height, good insulation preformance, control rail length travel ability is strong; Assemble easy accessibility than glueing joint insulating joint, applied range, and cost is low.
Fig. 1 freezes insulating joint structure assembling schematic diagram for the utility model rail;
Fig. 2 freezes insulating joint structure side view for rail.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
At first, thickening clamping plate 1 and troughing plate 2 factory with insulation glue-line 3 by setting technology the bonding splicing cleat insulator 4 that becomes a kind of integral body.
When on rail track, assembling, earlier put into fiber end post at the rail gap place of rail joint, in the both sides of rail the splicing cleat insulator is installed, in the bolt hole of rail and splicing cleat insulator, penetrate insulation sleeve and high-strength bolt is installed, after high-strength bolt torsional moment is according to the rules tightened repeatedly, then finished the assembly working that rail freezes insulating joint.At this moment, the geometry of Hubei Province and flange of rail end face contact site matches under splicing cleat insulator 4 and rail 5 rail heads, and can produce the above frictional resistance of 1200KN, effectively joint is freezed, and the prevention rail stroke, thereby improved the overall construction intensity of rail insulated joint, slowed down the right percussion of Train Wheel, the generation and the development of joint disease have been reduced, improved the stationarity of train operation, this kind rail freezes insulating joint, can install and use on rapid line, to adapt to the development of railway speed increase.
By the insulation glue-line 3 that contains glass fabric will thicken clamping plate 1 and troughing plate 2 in professional factory through sandblasting rust cleaning, operation such as assembling pressurization and heating cure and the bonding splicing cleat insulator 4 of making, have and the corresponding through hole of the bolt hole of rail 5 glueing joint on the cleat insulator 4, between its 2 bonding troughing plates 2 at a distance of the 18-20 millimeter.When installing on the line, the rust cleaning of at first the rail head lower jaw of rail 5 and flange of rail end face being polished, put into fiber end post 8 at the rail gap place of two one steel rails 5 then, in the both sides of rail 5 splicing cleat insulator 4 is installed, in the bolt hole of rail 5 and splicing cleat insulator 4, penetrate insulation sleeve 6 and high-strength bolt 7, high-strength plain steel washer is adopted at described high-strength bolt 7 two ends, forms the friction type high strength bolt auxiliary connection after bolt is tightened and tightened up, and freezes insulating joint thereby constitute rail.
Claims (5)
1, a kind of rail freezes insulating joint, comprise thickening clamping plate (1), insulation glue-line (3), rail (5), fiber end post (8), insulation sleeve (6), high-strength bolt (7), it is characterized in that: between described insulation glue-line (3) and rail (5), increase by 2 troughing plates (2), and will thicken clamping plate (1) and troughing plate (2) through heating cure and the bonding splicing cleat insulator (4) of making one with the glue-line (3) that insulate.
2, rail according to claim 1 freezes insulating joint, it is characterized in that: between described 2 troughing plates (2) at a distance of the 18-20 millimeter.
